The Economist says that what the airline industry needs is more competition.In the last thirty years after airline deregulation in the United States, we've seen the demise, acquisition or merger of TWA, Braniff, PSA, Western Airlines, Continental, Eastern, Northwest, Pan Am, Piedmont, and more, and by the end of this year, we'll lose US Airways as well. If there's any more competition, we'll end up with one airline, which will be the end of all competition.
